The specific steps of using human body silica gel are as follows:

1. Accurately weigh AB components according to the weight ratio of 1: 1; 2. Mix and stir the weighed component A and component B, and be sure to mix them evenly; 3. It usually takes about 5-8 minutes to vacuumize and remove bubbles with a vacuum machine; 4. Pour the vacuum silica gel into the mold, heat it in the oven for 8- 1 degree, and cure it for about 1 minute; 5, finally demoulding and taking out the product.

Human silica gel should not be mixed with concentrated silica gel (industrial silica gel) (used concentration container and stirring rod can not be contacted), and avoid mixing with compounds containing sulfur, phosphorus and nitrogen, otherwise silica gel will be "poisoned".
